Abstract

Background & Aims -This randomised prospective study was carried out to study and compare incidence of laryngopharingeal morbidity when laryngeal mask airway (LMA) was used as an alternative to endotracheal tube (ETT) in mechanically ventilated patients.

Methods –this study was carried out in 70 patients of age gp 18-60,ASAgr1-2,both sexes, posted for surgical procedure under GA of duration 30-120 min. These pts randomly divided into 2 gps-GpE(n-35)in which portex ETT used and Gp L(n-35) in which LMA used. Postoperatively reaction to extubation, laryngeal morbidity like soreness, hoarseness observed.

Result- We found incidence postoperative sore throat more in Gp E (57.4%)compared to Gp L(34.28%), Also incidence of hoarseness in Gp E(31.42) compared to Gp L(11.42%),While dysphagia found more in Gp L(22.85%)as compared to GpL(5.71).Complaints altogether was observed more in Gp E(71.42)than Gp L(51.42).

Conclusion- LMA is superior to endotracheal tube due to less incidence of postoperative laryngopharyngeal morbidity  though difference was statically insignificant ,also more precise symptoms like sore throat, hoarseness was more with ETT.

Keywords- Laryngopharingeal morbidity, Laryngeal mask airway, sorethroat, hoarseness, intubation
